A home run every time? You did say the ball has a higher velocity. I
have never that alum bats hit them farther.

Yeah, a whole whopping four miles per hour faster, how could a pitcher
possibly duck THAT??!!!

I was a pitcher and I dunno' but I managed to take a linedrive off a
wooden bat once.. I don't want it to go any faster at all
Scientific evidence that batted ball speed is faster for aluminum
baseball bats.

Given the amount of controvery over the metal versus wood bat issue,
there have been surprisingly few scientific studies comparing the
performance of wood and metal baseball bats. There is one paper from
1977, when aluminum bats were just beginning to assert their
prominence, which concluded that the batted ball speed of an aluminum
baseball bat was about 3.85 mph faster than a wood baseball bat.[1]
The study was conducted with six skilled college players during more
than a dozen batting practice sessions over a 5-day period. Each
player would take several swings with either a wood or aluminum bat
(randomly chosen), rest for 10 minutes, then take several swings with
the other bat. Balls were pitched from both pitching machines and
regular batting practice pitchers, but pitchers were found to be more
consistent. During the testing, the average pitched ball speed was
56.6 mph. Batted ball speeds were measured using a radar gun. Data was
collected for each player until 30 line drives were produced within a
certain range of locations in the outfield. The results were an
average batted ball speed (for line drives) of 88.6 mph for the wood
bat and 92.5 mph for the aluminum bat. A second phase of the study
attempted to explain the increase in performance of the aluminum bat
by comparing the size of the "sweet spot" for the two bats by locating
the center-of-percussion. The study found that the aluminum bat
appeared to have a larger COP than the wood bat.

Of course, I would rather not take half a wooden bat to the chest
either Do the metal ones break off?

D'oh...what about the results when the ball isn't lobbed to the plate?
